Optical Brighteners – All Types, Grades & Related Derivatives

Optical Brighteners, also known as Optical Brightening Agents (OBAs) or Fluorescent Whitening Agents (FWAs), are additives that absorb ultraviolet light and emit blue-violet fluorescence to improve the perceived whiteness or brightness of compatible materials. Different grades are used in textiles, paper, detergents, plastics and other industrial applications, subject to product suitability and availability.

OPTICAL BRIGHTENERS – INDUSTRIAL BRIGHTENING AGENTS Product Type: Optical Brighteners / Optical Brightening Agents (OBAs) / Fluorescent Whitening Agents (FWAs) Available Types: Textile-grade, paper-grade, detergent-grade, plastic-grade and other application-specific brighteners, subject to availability. Common Product Families: Stilbene-based, coumarin-based, distyrylbiphenyl-based and other fluorescent brightening agents, depending on the product. Available Forms: Powder, granules, liquid or formulated preparations, depending on the grade. Purity / Active Content: Multiple commercial grades may be available. Exact assay, active content and concentration must be confirmed for each product; no single purity range applies to all optical brighteners. Solubility: Water-soluble, dispersible or compatible with specific media, depending on the chemical structure and formulation. pH Compatibility: Product-specific; confirm the recommended range and test conditions from the technical data sheet. Applications: Suitable textile processing, paper manufacturing, laundry and detergent formulations, plastics, coatings and other compatible industrial applications, depending on the product grade. Performance Properties: Brightening effect, fluorescence, whiteness improvement, light stability, wash resistance and compatibility vary by product and application. Molecular Formula: Specific to the individual optical brightener. Molecular Mass / Molecular Weight: Specific to the individual substance; expressed in g/mol. CAS Number: Varies by exact product identity. Confirm the product name and Chemical Abstracts Service number from verified documentation. EINECS / EC Number: Product-specific; verify against the exact chemical identity. HSN Classification: Certain optical brighteners may be classified under headings associated with fluorescent brightening agents or other synthetic organic colouring matter. The applicable Indian eight-digit HSN code must be verified for the exact chemical or preparation before invoicing or export. Other Technical Specifications: Density, moisture, shelf life, ionic character, active content, solubility and storage requirements should be confirmed from the product's technical data sheet and safety documentation. Related Types and Derivatives: Related brightener grades, variants and derivatives may be available on request, subject to actual availability and confirmation of the intended application. IMPORTANT: Optical Brighteners are a broad product category and do not have one universal CAS number, molecular formula, molecular mass, purity or HSN code. Specifications may change according to the exact product, grade and intended purpose. Confirm the product's technical data sheet, Certificate of Analysis (where available) and Safety Data Sheet before purchase. Veltheron Imperial Group Private Limited.
